A drilling contractor's view of underbalanced drilling ///

This article is not a technical discussion of underbalanced drilling (UBD). It is a discussion about the best method – from one drilling contractor’s view – to execute a safe and productive UBD project. There is no magic formula, no exotic management technique and no revolutionary equipment design that will guarantee success. This is a frank discussion about the "mindsets" that operators and drilling contractors have when approaching a UBD project. The goal is to help both parties better understand the strengths, weaknesses, needs, concerns and objectives of each other to better deliver a successful project.
